Shohreh Posted October 5, 2022 Share Posted October 5, 2022 Hello, To migrate a PHP application, I need to install and configure nginx to use PHP 5.x, migrate the app, and then upgrade to PHP 7.x to manage the new version. What's the right way to handle this? Can I simply run eg. "apt install php5.6-fpm php7.4-fpm", and edit nginx's configuration file to point to the right FPM at the right step? Thank you.

requinix Posted October 5, 2022 Share Posted October 5, 2022 Do you actually have both php5.6-fpm and php7.4-fpm available to install? Quote Link to comment https://forums.phpfreaks.com/topic/315402-using-php-fpm-5x-and-then-7x/#findComment-1601353 Share on other sites More sharing options...
Shohreh Posted October 5, 2022 Author Share Posted October 5, 2022 (edited) No, I don't. I'm investigating if it's doable. At this point, I have a working server with php7.4-FPM. The legacy app expects "phpBB 3.0.4: PHP 4.3.3+ (>=4.3.3, >4.4.x, >5.x.x, >6.0-dev (compatible))". I don't know the difference between the "php" package and the "php-fpm" package, especially since I read I shouldn't install the former since it relies on Apache, and therefore installs it. It sems rather easy:https://www.atlantic.net/vps-hosting/host-multiple-websites-with-different-php-versions-on-ubuntu-18-04-vps/ Edited October 5, 2022 by Shohreh Quote Link to comment https://forums.phpfreaks.com/topic/315402-using-php-fpm-5x-and-then-7x/#findComment-1601364 Share on other sites More sharing options...
requinix Posted October 6, 2022 Share Posted October 6, 2022 Wow, it's so old it claims to be compatible with PHP 6. If you're starting from PHP 5.x then you're probably around 5.3 or 5.4. Going to 5.6 as the next step is good and probably won't be too bad. Going to 7.4 is a significant leap that you may want to split into 7.0 first and then 7.4 after. Because breaking the upgrade process down into steps like that helps make it manageable - going from 5.x directly to 7.4 could easily be a tough slog that will take a long time without the end in sight. I assume there's more than just installing the most recent version of phpBB? Which is apparently still in active development?

Shohreh Posted October 6, 2022 Author Share Posted October 6, 2022 The joys of migrating… which explains why no one wants to do it and we end up with totally outdated and unsecure old servers. 5.6 should be fine to try migrating. A couple more questions: 1. Why does the php5.6 package contain no binaries? ~# apt-get download php5.6 ~# dpkg -c php5.6_5.6.40-63+0~20220929.69+debian11~1.gbp639d4c_all.deb drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/ drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/share/ drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/share/bug/ drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/share/bug/php5.6/ -rw-r--r-- root/root 25 2022-09-30 00:13 ./usr/share/bug/php5.6/control drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/share/doc/ drwxr-xr-x root/root 0 2022-09-30 00:13 ./usr/share/doc/php5.6/ -rw-r--r-- root/root 480 2022-09-18 14:52 ./usr/share/doc/php5.6/NEWS.Debian.gz -rw-r--r-- root/root 82584 2022-09-30 00:13 ./usr/share/doc/php5.6/changelog.Debian.gz -rw-r--r-- root/root 178252 2022-09-30 00:13 ./usr/share/doc/php5.6/changelog.gz -rw-r--r-- root/root 21026 2022-09-18 14:52 ./usr/share/doc/php5.6/copyright 2.

The FPM daemon? FastCGI? Just the CLI? Debian/Ubuntu separate PHP into multiple subpackages. "php5.6" is a metapackage with only a handful of files itself. You typically install the more specific packages in addition/instead. 4 hours ago, Shohreh said: 2. To install php on nginx… how to prevent it from installing Apache as well? Is installing php-fpm enough to run PHP on nginx? nginx and php-fpm are separate. You install and configure both individually. Apache and mod_php are not separate because that approach has PHP as an Apache module so they're directly related. It's the traditional configuration, and one that's mostly fallen out of favor.

Shohreh Posted October 9, 2022 Author Share Posted October 9, 2022 Thanks for the infos. I found how to install two version of PHP-FPM, and configure nginx to use a given version for a given directory.
